“In one of the previous instructable, we saw how to make a simple thermometer with ATTINY 85 which can last for 140days with a single battery and it still works great after 40+ days with the same battery I showed in the video.
But it was a tiny bit clumsy when it came to the electronics and the programming. So, in this instructable, let me show you how to make a thermometer on steroids with features nobody asked for, but by doing so I hope you will definitely learn plenty of electronics along the way.
The device will have the following features:
- Realtime reading using WebSockets
- Auto sleep on when not in use
- Control the thermometer from a webpage
- Sleek PCB design
- Integrated esp-01F programmer
- Integrated lipo charging circuit
- 3d printed case
These are the list of products that can help you do this project with ease
- ESP-01F
